Purgeable in Disk Utility

There is a large section on HDD that states purgeable in Apple, About and in disk utilities.  It's available space but how do you purge or see what's there?

• In macOS Sierra, “Purgeable” content appears when you've turned on Optimize Mac Storage. It's storage space that your Mac can automatically make available when storage space is needed. Files marked as purgeable can always be downloaded again on demand.

• In macOS Sierra, “Purgeable” content appears when you've turned on Optimize Mac Storage. It's storage space that your Mac can automatically make available when storage space is needed. Files marked as purgeable can always be downloaded again on demand.

Can you uncheck "Optimize Storage".  

Thanks,

This got me back to default.   The Purgeable size is huge.  Does it reduce over time?

I have purgeable space accumulating but "Optimize Mac Storage" is disabled.   Should this occur?

I was using bootcamp I have 20 gb of purgeable space how to convert that to free space

Same for me. I did not select the optimize function, but found that 40gb of my files had been arbitrarily and randomly tagged as purgeable by the system. Including new files that I did not want removed from my HD. This was a week ago.

Then yesterday, those files were purged. For no apparent reason or trigger. Are they gone forever? How to prevent more files from being purged? Who knows, cos Apple aren't giving any info or options on how to manage or prevent this.

If you have TimeMachine enabled it might be that local snap shots are the issue.  Generally when the backups are successfully completed, the OS will delete the local snapshots.   I have seen a delay in this which causes the local snapshots to remain.

An option is to disable local snapshots but know that this will delete any TimeMachine local backups created between TM backups.  It not delete any files other than the backups that have not been written to TimeMachine.

The command to disable snapshots is:

sudo tmutil disablelocal and must be run from a terminal session.  It will also prompt for an admin password.

To renable use:

sudo tmutil enablelocal

Hope this helps.

Thanks Chastings.. I did what you stated in your post and my purgeable space was reduced to almost negligible.

Thanks Chastings -- that was exactly my issue here as well. I'd disabled iCloud Drive and the purgeable space was not being reclaimed (subtracted from the "free space") and reported erroneously. I hope future point releases make this easier to DISABLE completely, and revert to the previous OSX ("pre-MacOS"? lol) behavior.

Super helpful. Worked perfectly. I have a feeling this answer is going to help others.

thank you. got rid of 130 gb!

Thank You!

Thanks , released 10 gb from my drive !
